Description

PJHKEYPropEdit.pas defines a property editor for properties of type HKEY – i.e. registry root keys. The editor causes a drop-down list of all the registry root keys supported by Delphi to be displayed in the object inspector for any property of type HKEY.

Such a property is exposed by my TPJRegWdwState component. This property editor is included with current releases of that component.

Compatibility

The property editor compiles and works with all versions of Delphi from Delphi 2. It has been tested with Delphi 2, 3, 4, 5, 7 and 2006.
